Chris H has got it right just check the wire. If the wire is there it doesn't matter what the country code is as bikes get shipped around the world all the time. Say for instance there is a dock foreman and he says "Ok sheet says here we need to ship 100 bikes to France, ooops we only have 99" "Suzuki say ok we'll send over another bike, damn we only have the Japanese/restricted ones assembled for shipping. What the hell the customer probably won't notice or care" The limiter also only limits RPM sent by the ignition coil so if you can get 185km doesn't mean it's not restricted because it went an extra 5km over, it just shows the speedometer error as Suzuki clocks the bike at a track at 180 and just pegs the rpm at whatever that is. If you wanted to test it without going through wiring, but its alot more work, is put the smallest sproket you can on the front which will fool the CDI unit into thinking your going faster than you really are, if you speed now tops out at say 150-160 then you know %100 you're being limited. If not than thats all the bike will give you without jetting and piping it. What is the top rpm it reaches at 185? is it alot below redline?
